Before tackling typical HD simulation results, it is worth to review a few common physical and numerical properties of metals leveraged by investigations of different groups. A key small-scale feature of metals is that they are passive tracers of the hydrodynamical evolution; thus, they can be used akin to dyes/pollutants in fluid dynamics studies [1]}.
In hydrodynamics [2]},
the equation describing the temporal rate of change of the metal tracer density is given by
(in the Eulerian/grid framework):
\( \frac{\partial \rho _{Z}}{\partial t} + \div {(\rho _{Z} {v}) = S_{Z}},\)
